Net Server Case Review
When you look inside your computer can you actually see the motherboard or is it
simply a mess of cables, cards and drives (like mine). Could be that you've
outgrown your little mid-tower and its time for a case upgrade. Just
consider for a second how a cramped case can adversely affect your computers
performance; decreased air flow being one of the deciding factors in higher case
Given a hot case
it's usually a good idea to cut a few holes and install some 90mm
fans to improve air flow. While that will work well
for most cases, the benefits start to be less obvious if there is just a shear
number of devices crammed into the case that are causing the temperature problems. Solution - upgrade the case to a
the best upgrades these days seems to be the Aopen HX08, but what if that isn't
big enough? What if you're running an FTP, or just have A LOT of gear to pack in
Time to move into the big leagues and get a server case. Hey we don't go
half-assed and get one of those candy coloured iMac wannabe's around here.
Enter the Net Server Case A9891.

First off I think it's best to mention the number nine. Why? Because that is
the number of fans this case can take without any modifications! Truly we are
in the world of server cases. Focusing in on just the motherboard compartment
for the moment, there are two 92mm fans which pull in cool air (through an air
filter no less) and help to keep things like your processor and slot
cards, nice and cool.
Considering that 92mm Rodale fans can range in power from 27-60CFM, and Nidec
fans from 28-62CFM; that's potentially 120-124CFM of fresh air being brought in
to cool the motherboard, slot cards, and CPU. This case is made to cool
some seriously toasty devices for sure.
With the mid-tower class of case, too many devices lead to too many
wires which clog up free space and inhibit air flow. The Net Server's
compartment housing the motherboard and similar devices is about 7.5" deep,
leaving about 2.5" inches of space over-top of the slot cards - plenty of room
for good airflow and tones of cables.

Even the largest of heatsinks could fit into this case without any
difficulties, having its' cooling prowess aided by the rear air vents to boot.
Most, but not all mid-towers have some type of perforated venting on the backs
of their cases, but the Net Server Case has it where it really counts - directly
behind the CPU. A space of 6"x2.5" is prefaced with 0.25" circular holes, and
has a mounting bracket to accept a 60mm fan. With 8-25CFM fans of this type
coming from Nidec, the motherboard compartment could be drawing in 124CFM, and
force exhausting 25CFM directly behind the CPU.
The drive compartment of the case can be stacked with three 80mm intake fans (i.e.
blowing cool air over a rack of SCSI drives to keep them from burning up) and
one large 120mm exhaust fan if the 3.5HDD rack isn't used (or a 92mm fan if it
is). Using Nidec fans that's potentially 129CFM of intake and 130CFM of exhaust
on one side of a case!! Impressive, noisy, but impressive. I think this case
packed with every possible fan would just be to noisy to deal with for the office,
but even without any of the fans the shear volume of the Net Server case works
towards keeping everything close to room temp. Now, there is plenty of space
to install a really good liquid cooling rig - but that's for another weekend.
